Sympy 简明教程

SymPy - Installation

SymPy 有一个重要的先决条件库，名称为 mpmath 。这个 Python 库用于任意精度的实数和复数浮点运算。但是，在按以下方式安装 SymPy 时，Python 的软件包安装程序 PIP 会自动安装它 -

SymPy has one important prerequisite library named mpmath. It is a Python library for real and complex floating-point arithmetic with arbitrary precision. However, Python’s package installer PIP installs it automatically when SymPy is installed as follows −

pip install sympy

其他 Python 分发包（如 Anaconda、Enthought Canopy 等）可能已将 SymPy 内置其中。要验证，可以在 Python 提示符中键入以下内容 -

Other Python distributions such as Anaconda, Enthought Canopy, etc., may have SymPy already bundled in it. To verify, you can type the following in the Python prompt −

>>> import sympy
>>> sympy.__version__

然后你将获得如下 SymPy 当前版本输出 -

And you get the below output as the current version of sympy −

'1.5.1'
